MILLINOCKET, Maine — A Millinocket man was being held at the Penobscot County Jail in Bangor on $25,000 cash bail Monday after his girlfriend told police that he briefly held a knife to her throat during an argument, police said.

Cole Joseph Lyons, 25, was charged late Saturday night with and Class B aggravated assault and Class D assault and taken to the jail, Officer Kevin Ingersoll said.

The woman suffered minor injuries, two small cuts under her chin, for which she declined treatment at the scene, Ingersoll said. Police also found a small Swiss Army-style knife that they believe was used in the incident.

The incident began for police at about 7:45 p.m., when they received a 911 call from the woman at her apartment. When they arrived, she told officers that she and her boyfriend had been arguing earlier on a street near her home, Ingersoll said.

At some point, the woman claimed, Lyons put a knife to her throat after wrapping his arms around her briefly before she broke free and the argument continued, Ingersoll said. After he left, she called 911.

Police arrested Lyons at his Maine Avenue apartment a few hours later.

Police said they are still working to determine exactly what happened and why. More interviews are scheduled for today.

“Her story is one way; his is another,” Ingersoll said Monday.

Lyons is due to make his initial court appearance on Feb. 27 at Bangor District Court, a jail spokesman said.
